This data collection focuses on adult cases of serious
crime such as homicide (and related death investigations), rape,
robbery, aggravated assault/battery, burglary, and arson. Data are
included for Peoria, Illinois, Chicago, Illinois, Kansas City,
Missouri, and Oakland, California. The data consist of police, court,
and laboratory records from reports submitted by police personnel
during investigations of suspected criminal offenses. The primary
source of information was police case files. Prosecutor and court
files were reviewed for information regarding the disposition of
suspects who were arrested and formally charged. Crime laboratory
reports include information concerning the evidence submitted and the
examiner's worksheets, notes, and final results. There are eight
files in this dataset. Each of the four cities has one file for cases
with physical evidence and one file for cases in which physical
evidence was not collected or examined.
